Human versus machine: a comparison of the accuracy of geographic profiling methods

The current article addresses the continuing debate as to the accuracy of geographic profiling methods in predicting the location of serial crime offenders. In particular, the research addresses whether spatial distribution methods and humans using simple heuristics are as accurate at predicting home locations of offenders as more complex algorithm‐based methods such as RIGEL, DRAGNET, and Crimestat. Using a random sample of solved serial crimes, the research found that predictions by human judges and spatial distribution methods performed equally as well as more complex algorithm‐based methods. In addition to a discussion of findings, implications for police investigations and researchers are included. Copyright © 2006 John Wiley & Sons, Ltd.     

从东西方文化的差异分析面子与自尊的关系

":面子"对于中国人的重要性就像是"自尊"之于西方人一样,本文通过从东西文化的差异深入分析了面子与自尊间的联系与区别,认为涉及两者的心理过程是类似的,但是面子却又比自尊负载了更多社会学上的价值,因此,建议在未来的面子研究中,分别尝试从心理学与社会学两个层面加以入手,以期为相对滞后的面子研究注入新的活力。     

基于增长模型的非随机缺失数据处理:选择模型和极大似然方法

对含有非随机缺失数据的潜变量增长模型,为了考察基于不同假设的缺失数据处理方法:极大似然(ML)方法与DiggleKenward选择模型的优劣,通过Monte Carlo模拟研究,比较两种方法对模型中增长参数估计精度及其标准误估计的差异,并考虑样本量、非随机缺失比例和随机缺失比例的影响。结果表明,符合前提假设的Diggle-Kenward选择模型的参数估计精度普遍高于ML方法;对于标准误估计值,ML方法存在一定程度的低估,得到的置信区间覆盖比率也明显低于Diggle-Kenward选择模型。     

学生感知的教师欺凌态度与学生欺凌行为的关系——学生欺凌态度的中介作用及其性别的调节作用

校园欺凌严重影响青少年身心的健康发展,教师是预防和干预校园欺凌的重要力量。本研究拟在考察学生感知的教师欺凌态度与学生欺凌行为关系的基础上,探究学生欺凌态度的中介效应以及性别的调节作用。本研究采用《校园欺凌量表》、《学生欺凌态度量表》以及《学生感知的教师欺凌态度量表》对来自北京市两所初中的698名初一和初二学生进行测查。结果显示:(1)初中男生总体及不同类型的欺凌行为及其欺凌态度均显著高于女生,而女生所感知的教师欺凌严重性态度则显著高于男生;(2)学生感知的教师欺凌严重性态度显著负向预测学生欺凌行为;(3)学生欺凌态度在学生感知的教师欺凌态度和学生欺凌行为之间起部分中介作用;(4)学生欺凌态度的中介效应存在显著性别差异,男生欺凌态度为部分中介作用,而女生欺凌态度为完全中介作用。     

压力下一搏：压力如何影响个体风险寻求

压力促使个体风险寻求已得到许多研究的验证和支持, 但对于该现象背后的根本机制缺乏深入探讨和整合。模型指出, 压力诱发认知资源损耗和心理需要失衡, 导致个体执行控制功能减弱, 奖赏寻求增加, 这两者引起对风险选项价值的高估、风险感知的降低和启发式决策策略的使用, 最终导致风险寻求。期望效用论、预期理论、双系统理论和风险敏感理论的视角能各有侧重地解析模型中的路径。最后, 基于模型梳理了边界条件, 并提出未来可关注压力下执行功能、认知和情绪的交互以及慢性压力的影响和调控。     

The Influence of Religion and Spirituality on HIV Prevention Among Black and Latino Men Who Have Sex with Men,New York City

Ethical and Legal Issues Addressing the Use of Mobile Health (mHealth) as an Adjunct to Psychotherapy

mHealth refers to the rapidly evolving use of mobile devices for health care treatment purposes, particularly the use of apps and texting as adjuncts to psychotherapy. Although there is currently an extensive literature on issues related to telehealth, to date little guidance has been developed to help professionals function ethically in the rapidly emerging area of mHealth. This article identifies the major ethical considerations that need attention and proposes several recommendations to address mHealth use as an adjunct to psychotherapy, including the pressing need for relevant American Psychological Association practice guidelines to assist mental health providers in the ethical implementation of mHealth.

非那雄胺与前列腺癌发病率及病理分级的Meta分析

应用Meta分析法对有关非那雄胺与前列腺癌发病率及病理分级关系的研究进行综合评价.符合标准的8篇文献进行Meta分析,计算比值比(OR),95%可信区间(95%C1).结果8篇文献,无异质性(Q=6.26,P=0.51),非那雄胺治疗组降低前列腺癌发病风险高于对照组,合并OR值为0.68(95%CI:0.65～0.71,Z=17.16,P=0.00).Egge:检验提示无发表偏倚(P=O.21).对前列腺癌病理分级进行分组,非那雄胺治疗组前高于对照组.合并OR值为2.16(95%CI:1.97～2.36,Z=16.93,P=0.00).非那雄胺治疗前列腺增生能降低前列腺癌的发病风险,也能使发生的前列腺癌的病理级别增高.
